Refresh button

I noticed that there was some talk in earlier threads about a refresh button and auto-refresh. I would like to put in a vote for a refresh button. I use Toodledo in the Google Chrome Application Shortcut format. Basically, it is Chrome's version of Prism. Anyhow, there is no browser refresh button. So it is difficult to get my Toodledo to refresh after adding a new task and/or making any changes.
Thanks!
